aquagroup AG

aqua.complete is the all-round-service of aquagroup AG for all operators of evaporative cooling systems and wet scrubbers. NADES 2.0, our oxidative biocide is generated on site, requiring only water, salt and electricity as commodities. Used in automated processes in low concentrations for the removal of biofilm it eliminates germs, such as Pseudomonas aeruginosa, Legionella spp. and thus guarantees sustainable, perfect cooling water hygiene as well as the fulfillment of hygiene requirements in accordance with the new ordinance.

Thanks to the team of VDI experts and trained employees in the fields of technology and microbiology, aquagroup offers operators of evaporative cooling systems and wet scrubbers all-round-service in the context of the 42nd BImSchV, from sampling and risk assessment to a broad portfolio of equipment, measuring and control technology specially adapted to cooling towers, inhibitors, etc.

Our biocidal product NADES 2.0 is an electrochemically activated (ECA) solution which is produced through our specially designed devices. A saturated brine solution (NaCl) is pumped through an electrolysis cell and  sodium hypochlorite is formed. The unique electrodes guarantee a stable and failsafe production. All device’s components are simple to operate.

There is no handling of hazardous goods because of the automated processes. NADES 2.0 is effective against biofilm and due to its high anti-microbiological efficacy it eliminates germs like Pseudomonas aeruginosa, Legionella spp.

 NADES 2.0 and the aquagroup devices guarantee a sustainable and perfect hygiene for cooling water (according to 42. BImSchV.) and form the basis to meet the requirements according to the new regulation.

Independent, accredited laboratories proved the efficacy of NADES 2.0 against Legionella spp., according to DIN EN 11731 and DIN EN 13623. There is no known development of resistance.

NADES 2.0 is more than ordinary sodium hypochlorite

• No hazardous good
• High efficacy
• No resistance: one biocide, no alternating necessary
• No storage capacities necessary (excl. salt), just in time
• Economically friendly
• Automated processes (central production)
• Safety at any time due to monitored dosing
• Low operating costs
• Saving of working time

In open cooling systems the protection of corrosion, reliable stabilization of water hardness as well as the control of microbiological activity pose the most important part of the treatment agents. aquagroup AG gladly assists to find the optimal choice of product or product combinations.

Our product FC370 serves as hardness stabilization as well as corrosion inhibitor and is a universal product for open cooling systems.

Note: Use biocides safely. Always read the label and product information.

Our cooling tower measuring and controlling technology "aqua.complete" is a fully equipped controller for monitoring and setting optimum cooling water quality in evaporative cooling systems.

aqua.complete is a fully featured cooling towers controller with two-way biocide options and inhibitor / bleed control.

The compact mCON generator produces NADES 2.0, an electrochemically activated solution (ECA) based on electrolysis (sodium hypochlorite 4,000 – 6,000 ppm). The fully automated device consists of an electrolysis cell, brine dosing pump and an integrated microprocessor control, which is located in the switch cabinet.

The electrolysis system is supplied with a salt container ready to connect (optional if not available: water softener and storage tank). It is only required to install the water pipes and to connect salt tank and product storage tank. The device is easy to handle, robust and reliable.

We will integrate the mCON generator into your existing system and offer you a wide range of matching accessories, such as softeners, pumps, tanks, online measurements, etc.

Advantages:

• Stable production and quality
• No waste product
• Simple and safe handling
• Robust and reliable
• No hazardous good
• Service
• Expertise

Besides the well-known advantages (for example low purchasing costs, reduction of biofilm, no transport of dangerous goods, no storage of hazardous material), the low operating costs compared to chlorine dioxide systems are crucial. Due to these facts, customers decide in favor of the mCON-generator.
